PERHITUNGAN INTERAKSI ANTAR NANOPARTIKEL MAGNETIK DAN MAGNETISASI DALAM LAPISAN TIPIS COBALT SAMARIUM MENGGUNAKAN SOFTWARE MATLAB R2015a

---

The calculation of magnetic nanoparticles interaction and magnetization in thin film of samarium-cobalt using MATLAB R2015a Software has been performed. The computer consisted of two program that is program menu and main program. The data entered in the program menu are DCD and IRM magnetization values obtained from measurements using alternating gradient force magnetometer (AGFM). The next step, the main program will calculate magnetic nanoparticles interaction and magnetization and displays the results in graphical form. Samarium composition was varied from 10%, 13%, 16%, 22%, 35% and 40%. The results show the interaction is positive in the sample, except for samarium 16% of the value of a negative interaction (-0.4 Arb.Unit), meaning that from the nature of dipolar interactions. Sample magnetization value decreases linearly from the composition of 10% to 40%, ie 1085,33
to 226,23
, while the value of coercivity rises with the addition of samarium composition up to 16%, and maximum values contained in the composition of 16%, ie 2052.17 Oersted. Adding of SmCo reaction above 16 at % Sm produced small value of coercivity of the films.
Keywords : samarium-cobalt, composition, magnetic nanoparticles interaction, magnetization, coercivity, MATLAB.
