The Ni48Fe12Cr40 film with thickness of 5 nm has been found to be X-ray amorphous and exhibits negative temperature coefficient of resistance. The observation of anisotropic magnetoresistance, as well as anomalous and planar Hall effect, indicates the presence of ferromagnetic ordering in this sample. The increase of the Ni48Fe12Cr40 film thickness to 8 nm leads to the crystallization and texture formation, which promotes more uniform distribution of Cr atoms in Ni-Fe matrix and suppression of the long-range ferromagnetic order.
