Abstract
We have studied the Nb(70 nm)/Ni0.65Cu0.35(6.5 nm)/Si layered structure in the temperature range T = 1.5–10 K using polarized neutron reflectometry. The correlation of the states of magnetic structures is observed at temperature T = 9 K, which is slightly higher than the superconducting transition temperature Tc = 8.5 K of the structure. At temperature T = 4 K, which is lower than Tc, the effect of reflexivity of magnetic states existing at T = 9 K was observed.
