Field-induced spin-flop transitions in α-MnMoO are summarized in magnetic H-T phase diagrams for different directions of the applied magnetic field up to 12 T. The antiferromagnetic arrangement in the spin-flop phase is preserved at least up to this field for a field parallel to the easy ...

The magnetic and electrical transport properties of Mn-doped amorphous silicon ( extit{a-}Mn$_{x}$Si$_{1-x}$) thin films have been measured. The magnetic susceptibility obeys the Curie-Weiss law for a wide range of $x$ (0.005-0.175) and the saturation moment is small. While all Mn...
and magnetic moment has long been noted.6This correlation is readily seen by comparing the atomic concentrations of the first, second and third transition series elements as shown in Fig. 1, where the densities for the second and third series elements have been scaled for comparison with the fi...
Spintronics, which is the basis of a low-power, beyond-CMOS technology for computational and memory devices, remains up to now entirely based on critical materials such as Co, heavy metals and rare-earths. Here, we show that Mn4N, a rare-earth free ferrimagnet made of abundant elements, ...
(4.10)μB=eh/4πmc=0.927×10−20erg/Oeor0.927×10−24Am2 When a magnetic material is subjected to an external magnetic field (H) it gets magnetized. The magnetization (M) of a material is defined as the magnetic moment per unit volume (V). (4.11)M=m/V The magnetic susceptibility...
It was an established fact that Fe+3 ions contain the magnetic moment of 5μB/f.u., while the Fe+2-ions attain magnetic-moment of 4 μB/f.u. Indeed, this aspect implied a fact that the increasing La-content reduced the resultant magnetic moment thereby increasing the concentration of ...
The temperature dependence of the magnetisation is also attributable, for the main part, to the same mechanism, whereas thermal variation of the moment carried by these atoms remains nearly constant. The temperature dependence of the magnetisation is also attributable, for the main part, to the ...
The net magnetic moment depends on the thermal treatment regime used to synthesize a specific sample. Fe3O4 is a parent representative of other magnetic ferrites, MFe2O4 (M = Mn, Co, Ni), with the inverse spinel structure. The degree of inversion, i.e., the concentration of the M2 +...
The crystal and magnetic structures of RbMnF4 and KMnF4 have been determined by neutron powder diffraction. The crystal symmetry of both compounds belongs to the layered perovskite structure and exhibits a pseudo-tetragonal unit cell, space group P21/a. The (MnF2F42/)- octahedra show a distort...
