Change of electron state density in V2Zr compound under radiation induced disordering

Cooperative analysis of temperature dependences of magnetic susceptibility, nuclear magnetic resonance and the rate of spin-lattice relaxation of 51V nuclei in V2Zr intermetallic compound, subjected to fast neutron fluence (up to 3 x 1024 m-2 doses) was conducted. Change of main contributions to magnetic susceptibility under radiation induced disordering was traced. Evaluations of electron state density on Fermi level were obtained: decrease of critical temperature under disordering was accompanied by its sufficient decrease on Fermi level
