Journal ArticleDOI
Mechanical alloyed Ho3+ doping in CoFe2O4 spinel ferrite and understanding of magnetic nanodomains
TL;DR: In this article, the structural and magnetic properties of CoFe1.95Ho0.05O4 spinel ferrite were analyzed using X-ray diffraction, SEM, thermal analysis (TGA and DTA), and VSM measurement.
Journal ArticleDOI
Surface magnetism, Morin transition, and magnetic dynamics in antiferromagnetic α-Fe2O3 (hematite) nanograins
R.N. Bhowmik,A. Saravanan +1 more
TL;DR: In this article, the grain size of α-Fe2O3 decreases to ∼20nm by 64 h mechanical milling of the bulk sample and the core-shell structure also plays an important role in exhibiting the increasing soft ferromagnetic character in the present hematite samples.
Journal ArticleDOI
Magnetic enhancement in antiferromagnetic nanoparticle of CoRh 2 O 4
TL;DR: In this paper, a core-shell model was proposed for the magnetization of nanoparticles, with the core retaining its antiferromagnetic order and the enhancement of magnetization below the threshold.
Journal ArticleDOI
Anomaly in cluster glass behaviour of Co0.2Zn0.8Fe2O4 spinel oxide
R.N. Bhowmik,R. Ranganathan +1 more
TL;DR: In this paper, the authors reported the appearance of shoulder in AC susceptibility data at T f2 ≈212 K can be explained in terms of freezing of larger size clusters associated with anisotropy distribution, rather than spin-glass-like freezing.
Journal ArticleDOI
Lattice expansion and noncollinear to collinear ferrimagnetic order in a MnCr 2 O 4 nanoparticle
TL;DR: In this article, the magnetic behavior of spinel chromite nanoparticles has been investigated and the correlation between a systematic increase of lattice parameter and the gradual decrease of $B$ site non-collinear spin structure has been shown.
