摘 要:Interface engineering is an effective and feasible method to regulate the magnetic anisotropy of films by altering interfacial states between *** the technique of pulsed laser deposition,we prepared La_(0.67)Sr_(0.33)MnO_(3)(LSMO)and La_(0.67)Sr_(0.33)MnO_(3)/SrCoO_(2.5)(LSMO/SCO)films on(110)-oriented La_(0.3)Sr_(0.7)Al_(0.65)Ta_(0.35)O_(3) *** covering the SCO film above the LSMO film,we transformed the easy magnetization axis of LSMO from the[001]axis to the[110]axis in the film *** on statistical analyses,we find that the corresponding Mn-Mn ionic distances are different in the two types of LSMO films,causing different distortions of Mn-O octahedron in *** addition,it also induces diverse electronic occupation states in Mn^(3+)*** e_(g) electron of Mn^(3+)occupies 3z^(2)-r^(2) and x^(2)-y^(2) orbitals in the LSMO and LSMO/SCO,*** conclude that the electronic spin reorientation leads to the transformation of the easy magnetization axis in the LSMO films.
