Sandwiches made from Fe and Cs films are investigated as a function of the magnetic field and the Cs thickness. Conduction electrons which cross from the Fe to the Cs are marked by a drift velocity component perpendicular to the electric field. The anomalous Hall effect in the Fe provides this "non-diagonal" kick to the electrons that cross from the Fe into the Cs. The ballistic propagation of the conduction electrons can be monitored as a function of the Cs film thickness. The free propagation into the Cs is measured in terms of the non-diagonal conductance Lxy which we denote as the "induced anomalous Hall conductance" L 0 xy . For a normal (non-magnetic) metal in contact with Fe, Lxy increases with the thickness of the normal metal until the film thickness exceeds (half) the mean free path of the conduction electrons. For Cs on top of Fe the induced anomalous Hall conductance increases up to a Cs coverage of about 100 A, then, in contrast to other non-magnetic metals, L 0 xy decreases for larger Cs coverage and approaches zero. This behavior cannot be explained with the free electron model. The strange behavior of the induced AHC in Cs films adds an even more challenging mystery to the already poorly understood properties of thin Cs films. These results defy explanation in the free electron model.

“…Since the Lifshitz-Kosevich theory [1] provided a basis for universal quantitative description of magnetic quantum oscillations, these effects became one of most popular experimental means of studying the Fermi surface properties of metals [2,3]. Besides traditional metals, quantum oscillations of magnetoresitance (Shubnikov -de Haas, SdH effect) and magnetization (de Haasvan Alphen effect) have recently proved extremely useful in exploring more complex topical materials such as cuprate [4,5] and iron-based superconductors [6][7][8], topological insulators [9][10][11], heavy fermion compounds [12][13][14], and organic charge-transfer salts [15][16][17].…”

We present magnetoresistance studies of the quasi-two-dimensional organic conductor κ-(BETS)2Mn[N(CN)2]3, where BETS stands for bis(ethylenedithio)tetraselenafulvalene. Under a moderate pressure of 1.4 kbar, required for stabilizing the metallic ground state, Shubnikov -de Haas oscillations, associated with a classical and a magnetic-breakdown cyclotron orbits on the cylindrical Fermi surface, have been found at fields above 10 T. The effective cyclotron masses evaluated from the temperature dependence of the oscillation amplitudes reveal strong renormalization due to many-body interactions. The analysis of the relative strength of the oscillations corresponding to the different orbits and its dependence on magnetic field suggests an enhanced role of electron-electron interactions on flat parts of the Fermi surface.

“…In heavy rare earth metals, the Fermi surface (FS) topology is determined by the crystal lattice parameters [29], to a point where heavy 4f elements are well-modeled by a crystallomagnetic phase diagram [30]. Experimentally, the ratio between the interplanar spacing c and the interatomic, intraplanar spacing a of the hexagonal-close-packed lattice, c/a, which is linked to ε α2 , seems to be the crucial parameter that triggers the electronic topological transition [31][32][33][34][35], supporting the nesting hypothesis [36] that links the appearance of webbing features in the FS topology to the onset of noncollinear magnetic ordering in rare earth metals.…”

Spin-flop transition driven by competing magnetoelastic anisotropy terms in a spin-spiral antiferromagnet

Holmium, the archetypical system for spin-spiral antiferromagnetism, undergoes an in-plane spin-flop transition earlier attributed to competing symmetry-breaking and fully symmetric magnetoelastic anisotropy terms [Phys. Rev. Lett. 94, 227204 (2005)], which underlines the emergence of sixfold magnetoelastic constants in heavy rare earth metals, as otherwise later studies suggested. A model that encompasses magnetoelastic contributions to the in-plane sixfold magnetic anisotropy is laid out to elucidate the mechanism behind the spin-flop transition. The model, which is tested in a Ho-based superlattice, shows that the interplay between competing fully symmetric α-magnetoelastic and symmetry-breaking γ -magnetoelastic anisotropy terms triggers the spin reorientation. This also unveils the dominant role played by the sixfold exchange magnetostriction constant, where D 66 α2 0.32 GPa against its crystal-field counterpart M 66 α2 −0.2 GPa, in contrast to the crystal-field origin of the symmetry-breaking magnetostriction in rare earth metals.
