Title: Paramagnetic Contribution To The Reversible Magnetization Of Nb3pt
Author: Kopelevich Y.
Moehleeke S.
Abstract: Reversible magnetization M(H,T) measurements are performed in a polycrystalline bulk and powdered sample of Nb75Pt25. An essential suppression of the diamagnetic moment is found below a field Hp(T) < Hc2(T) for the bulk sample, while for the powder it is not observed. This finding, as well as the resistance R(H,T,J) behavior typical of Josephson junctions, and oscillations of M(H,T) just below a Hp-Tp line strongly suggest a decisive role of the Josephson coupling (negative) in the occurrence of the paramagnetic contribution to the magnetization. The fully reversible magnetization excludes a trapped magnetic flux as an alternative explanation for the effect.
