- Аннотация: The effects of transition metal substitution for Ni on the magnetic properties of the YNi4B-type SmNi4B via SmNi3TB (T = Mn, Fe, Co, Cu) solid solutions have been investigated. SmNi4B, SmNi3MnB, SmNi3FeB, SmNi3CoB and SmNi3CuB show ferromagnetic ordering at 40 K, 210 K, 322 K, 90 K and 57 K and field sensitive metamagnetic-like transitions at 15 K, 100 K, 185 K, 55 K and 15 K in a magnetic field of 10 kOe, respectively. The magnetocaloric effects of SmNi3TB (T = Mn - Cu) were calculated in terms of isothermal magnetic entropy change (dSm). The magnetic entropy dSm reaches value of –0.94 J/kgK at 40 K for SmNi4B, –1.5 J/kgK at 205 K for SmNi3MnB, –0.54 J/kgK at 320 K for SmNi3FeB, –0.49 J/kgK at 90 K for SmNi3CoB and –0.54 J/kgK at 60 K for SmNi3CuB in field change of 0-50 kOe around the Curie temperature. They show positive Sm of +0.71 J/kgK at ~10 K for SmNi4B, +1.69 J/kgK at 30 K for SmNi3MnB, +0.89 J/kgK at 110 K for SmNi3FeB, +1.08 J/kgK at 25 K for SmNi3CoB and +1.12 J/kgK at 10 K for SmNi3CuB in field change of 0-50 kOe around the low temperature metamagnetic-like transition. Below the field induced transition temperature (change of magnetic structure), SmNi3TB (T = Mn - Cu) exhibits giant magnetic coercivity of 74 kOe at 5 K for SmNi4B, 69 kOe at 20 K (90 kOe at 10 K) for SmNi3MnB, 77 kOe at 60 K for SmNi3FeB, 88 kOe at 20 K for SmNi3CoB and 52 kOe at 5 K for SmNi3CuB.
