Peculiar magnetic properties of Er conditioned Ni43Co7Mn31Ga19 at ambient and hydrostatic pressures
Original language description
Recently, an attention has been paid to outstanding magnetic properties of martensitic phase of the Co-doped Heusler Ni2MnGa alloys with a paramagnetic gap that can be tuned by composition. We have prepared polycrystalline sample of Co doped Ni2MnGa alloy, Ni43Co7Mn31Ga19, with the very small amount of Er (0.1at.%). By the EDX analysis, a distinct segregation of Er was discovered in Er-rich phase while the main bulk material of the microcrystals was totally Er-free. Saturated magnetization M(5 K)= 3.27mu(B)/f.u. and the Curie temperatures T-C(A) = 453 K of austenite phase, were observed by a SQUID magnetometer on annealed sample and the standard magnetocaloric effect at vicinity of T-C(A) was measured by direct method with Delta T = 0.6 K. Magnetic susceptibility obeys nicely the Curie-Weiss law with paramagnetic moment of mu(eff) = 5.09 mu B/f.u. above T-C(A). However in the pronounced contrast with the Er-free alloys, both, the paramagnetic gap and mainly the martensitic transitions
