Giant anisotropic magnetostriction in Pr$_{0.5}$Sr$_{0.5}$MnO$_3$
Ramanathan Mahendiran,Clara Marquina,M. R. Ibarra,Anthony Arulraj,C. N. R. Rao,A. Maignan,B. Raveau +6 more
TL;DR: Magnetic, linear thermal expansion (LTE), anisotropic magnetostriction, and volume magnetostrictions of manganites were investigated in this paper, where the authors showed that the field induced antiferromagnetic to ferromagnetic transition is accompanied by a structural transition from the d$x^2-y^2}$ orbital ordered antifromagnetic (orthorhombic) to the orbital disordered ferramagnetic (tetragonal) phase.

Magnetic hydrogels derived from polysaccharides with improved specific power absorption: potential devices for remotely triggered drug delivery
Rebeca Hernández,Javier Sacristan,Laura Asín,Teobaldo E. Torres,M. R. Ibarra,Gerardo F. Goya,Carmen Mijangos +6 more
TL;DR: In this paper, a novel ferrogel derived from polysaccharides (sodium alginate and chitosan) with embedded iron oxide nanoparticles synthesized in situ and their combination with thermally responsive poly (N-isopropylacrylamide) for externally-driven drug release using AC magnetic fields was reported.

Unusual magnetic behavior in ferrite hollow nanospheres
Enio Lima,Jose M. Vargas,Roberto D. Zysler,Hercílio R. Rechenberg,Jordi Arbiol,Gerardo F. Goya,Alfonso Ibarra,M. R. Ibarra +7 more
TL;DR: In this paper, the authors reported unusual magnetic behavior in iron oxide hollow nanospheres of 9.3 $nm$ in diameter, which can be explained by the coexistence of a soft superparamagnetic phase and a hard phase corresponding to the highly frustrated cluster-glass like phase at the surface regions.
