C, alloys as heat capacity and electric resistivity in the temperature range 1.5 to 300 K, magnetoresistance in perpendicular and parallel magnetic fields up to = 4.78 X 10' A/m, magnetization, and the Mossbauer effect at 100 and 300 K are investigated. The data obtained are interpreted in t e r m of the hypothesis of short-range order and weakly-coupled "paramagnetic" centres in a ferromagnetic matrix. A phenomenological description of magnetoresistance data is given and a correlation with the Mossbauer data is discussed. npOBeAeH0 HCCJleAOBaHHe TenJIOeMHOCTH EI 3JIeKTpOCOIlpOTElBJIeHHfl aMOP@HbIX CIlJlaBOB FemB,, H Fe,,P,,C, B HHTepBaJIe TeMnepaTyp 1,s a0 300 K , MarHeTOCOIIpOTHBJIeHUfl B nepneHnnHynspHMx H napannenmmx nonfix AO w 4,78 x 1 0 ' A/m, naMarHmeHHocTn H a @ @ e~~a Mecc6ayapa npu TeMnepaTypax 100 u 300 K. nonyremble aamme umepnpe-TEl PYIOTCR Ha OCHOBe rHlTOTe3bI KOMl l OaWl IHOHHOTO 6 n~m~e r o IIOpflHKa EI cna6o CBR3aHHblX ,,llaPaMaI' HEITHbIX" UeHTpOB B @ePPOMal' HHTHOfi MaTpHUe. &aHO @eHOMeHOJIOrH9eCHOe OnH-CaHHe pe3yJIbTaTOB H3MepeHEIR MarHeTOCOl' lpOTHBneHHR H 06cy~c~ae~cfl HOppeJIflUHfl C MeCC6aY3pOBCKEIMH ,TJPHH€dMH.

The laser-induced mass transfer in thin-film substrate /Cr/Cu/Ni system is studied by means of Auger Electron Spectroscopy (AES). For the laser-pulse energy values, E = 100-170mJ, the diffusion of Cu atoms into Ni layer and their accumulation within this layer are observed, whereas at E > 170mJ the same is true for Cr atoms. The observed phenomena are explained on the basis of calculated temperature distribution in the system at issue during lased action. Enhanced transfer of Cr atoms towards external surface is observed under the irradiation regimes leading to the melting of intermediate copper layer. Diffusion coefficients of copper and chromium calculated from their surface accumulation show an exponential dependence on the laser-pulse energy. Under laser heating, the diffusion processes are more manifested as compared with those under conventional thermal annealing. This is bound up with higher concentration of nonequilibrium defects generated within the irradiation zone.
