Superparamagnetism and magnetic defects in Fe 2 VAl and Fe 2 VGa

We have investigated the magnetic properties of Heusler-type Fe2VAl and Fe2VGa by means of susceptibility, magnetization, and nuclear magnetic resonance (NMR) measurements. As evidenced by the static and dynamic magnetic susceptibilities, both compounds exhibit the characteristic features of a superparamagnetic glass. The freezing temperatures of our… CONTINUE READING
