Room temperature ferromagnetism in ZnO prepared by microemulsion

open access: yesAIP Advances, 2011
Clear room temperature ferromagnetism has been observed in ZnO powders prepared by microemulsion. The O vacancy (VO) clusters mediated by the VO with one electron (F center) contributed to the ferromagnetism, while the isolated F centers contributed to ...

A dynamical mean-field theory study of Nagaoka ferromagnetism [PDF]

open access: yes, 2007
We revisit Nagaoka ferromagnetism in the U=oo Hubbard model within the dynamical mean-field theory (DMFT) using the recently developed continuous time quantum Monte Carlo method as the impurity solver.

Thickness-Dependent Sign Change of the Magnetoresistance in VTe2 Thin Films

open access: yesSolids, 2022
Transition metal dichalcogenides of type VX2 (X = S, Se, Te) have recently attracted great interest as it has been predicted that they host ferromagnetism at room temperature. Whether ferromagnetism is indeed present is an open experimental question.

Ferromagnetism in proton irradiated 4H-SiC single crystal

open access: yesAIP Advances, 2015
Room-temperature ferromagnetism is observed in proton irradiated 4H-SiC single crystal. An initial increase in proton dose leads to pronounced ferromagnetism, accompanying with obvious increase in vacancy concentration.

Coexistence of Spin Canting and Metamagnetism in a One-Dimensional Mn(II) Compound Bridged by Alternating Double End-to-End and Double End-On Azido Ligands and the Analog Co(II) Compound

open access: yesMagnetochemistry, 2021
Two new compounds of general formula [M(N3)2(dmbpy)] in which dmbpy = 5,5′-dimethyl-2,2′-bipyridine, and M = Mn(II) or Co(II), have been solvothermally synthesized and characterized structurally and magnetically.

Significant enhancement of ferromagnetism in Zn$_{1-x}$Cr$_{x}$Te doped with iodine as an n-type dopant [PDF]

open access: yes, 2006
The effect of additional doping of charge impurities was investigated in a ferromagnetic semiconductor Zn$_{1-x}$Cr$_{x}$Te. It was found that the doping of iodine, which is expected to act as an n-type dopant in ZnTe, brought about a drastic enhancement

Full Variation of Site Substitution in Ni-Mn-Ga by Ferromagnetic Transition Metals

open access: yesMetals, 2021
Systematic doping by transition elements Fe, Co and Ni on each site of Ni2MnGa alloy reveal that in bulk material the increase in martensitic transformation temperature is usually accompanied by the decrease in ferromagnetic Curie temperature, and vice ...
