The behavior of magnetization in films of ferromagnetic inverted opal-like nanostructures based on cobalt and nickel is studied. The remagnetization curves M(H) and temperature dependences M(T) in the ranges of H from–50000 to +50000 Oe and T = 5–350 K are measured by magnetometry using a superconducting quantum interference device (SQUID-magnetometry). It is demonstrated that at T > 70 K, the...
