Phys. 110, 113908 (2011); 10.1063/1.3665035 Cluster-spin-glass behavior in layered LiNi 0.4 Mn 0.4 Co 0.2 O 2The magnetic properties of Cr-doped rhombohedral LiMnO 2 are investigated. Two paramagnetic regions are separated at 95 K with a reduction in the effective moment due to the change in spin-orbit coupling. Spin-glass-like behavior is suggested at low temperature based on the dc magnetization and magnetic hysteresis measurements.

Observation of spin glass behavior in monoclinic Li0.33MnO2

“…Lithium manganite such as rhombohedral LiMnO 2 [1,2], LiNi 0.5-Mn 0.5 O 2 [3], and spinel LiMn 2 O 4 [4] have attracted wide attention as cathode materials for Li-ion batteries because of their stable electrochemical performance, lower cost, and nontoxicity. On the other hand, lithium manganite also show rich physical phenomena due to its unique structural, orbital and charge characteristics.…”

Spin-glass-like behavior in rhombohedral Li[Li(1/3−x/3)Mn(2/3−2x/3)Nix]O2 (x=0.4)

“…The increase in the FC susceptibility below T irr is due to the occurrence of the finite range of inhomogeneous state around a quasicritical temperature [16,19,20]. A similar magnetic behavior has been reported for SGL system [21,22,23].…”

“…So the existence of SGL state may be mainly ascribed to the shortrange structural disorder, especially the disorder arrangement of Ni 3+ /Li + /Mn 4+ ions in the TM layers and of Li + /Ni 3+ in 3a and 3b sites. Such kind of scenario of random distribution of ions in the lattice associated with the formation of spin-glass-like behavior has been found in the Cr-doped rhombohedral LiMnO 2 [23].…”

A facile approach called nebulized spray pyrolysis to deposit MnS thin films: Effect of solution concentration with EDTA on the physical properties

“…The emission peaks at 361 nm and 374 nm correspond to the ultraviolet emission. It is worth to mention that the recent surge of activity in wide band gap semiconductors arising from the need for developing optical materials which are active in the UV wavelengths [27]. Thus, we believe that the NSP deposited MnS thin films can be used to develop ultraviolet light emitting and short wavelength optoelectronic devices.…”
