Magnetic behavior of isolated Mo impurities in antiferromagnetic Cr metal

摘要: Abstract We report experimental and theoretical studies on the magnetic moment hyperfine field of isolated Mo impurities in an antiferromagnetic Cr host. The response 92,94Mo, measured by means time differential perturbed angular distribution (TDPAD) technique, show saturation B hf ( 0 ) to be − 4.7 T . In addition, we find evidence short range spin correlation above N , revealed from observation large values at temperatures far Our ab initio calculations, based generalized gradient approximation (GGA) density functional theory (DFT), yield induced 0.45 μ for impurity Cr. magnitude calculated cal = 3.35 closely agrees with value. results presented this work would helpful a common understanding fields atoms ferro- materials.
