Structural and magnetic properties of ErFe2D3.1

Complex magnetic behaviour and evidence of a superspin glass state in the binary intermetallic compound Er5Pd2

“…Isothermal magnetization versus magnetic field curve was recorded in the temperature range of 2-100 K and the selected curves are displayed in Figure 2 also in canted AFM systems [4,20].The observed features in temperature and field magnetization described above has been reported for phase separated systems where ferromagnetic and antiferromagnetic phases co-exists, in glass-like magnetic state, highly anisotropic ferromagnets, in compounds with canted magnetic structure arising from competing AFM and FM exchange interactions and, occasionally, in high-anisotropic antiferromagnets with random orientations of crystallites [21][22][23][24]. Thus it appears that below the phase transition temperature the magnetic behaviour of the compound is quite complex.…”

A cluster-glass magnetic state in R5Pd2(R = Ho, Tb) compounds evidenced by AC-susceptibility and neutron scattering measurements

“…The hysteresis of the ZFC-FC susceptibility can be ascribed to the spin-glasses [29], cluster glasses [11,28], superparamagnets and superspin glasses [30]. Though the irreversibility in the ZFC-FC susceptibility behavior is usually considered as a hallmark of glass-like magnetic states it was also observed in highly anisotropic ferromagnets, in compounds with canted magnetic structure arising from competing AFM and FM exchange interactions and, sometimes, in high-anisotropic antiferromagnets with random orientations of crystallites as well [21,[31][32][33]. As follows from figure 3, a significant broadening and flattening of the susceptibility cusp and its shifting towards lower temperature is observed with the increasing field.…”

Phase diagram and order-disorder transitions in Y0.9Gd0.1Fe2Hx hydrides (x ≥ 2.9)

“…[6][7][8][9]. Interestingly, hydrogen insertion in RFe2 compounds yields strong magnetic properties changes [9][10][11][12][13][14][15][16]. Depending on the hydrogenation conditions, RFe2 hydrides can be either amorphous or crystalline [17][18][19].…”
