Controlling the exchange interaction using the spin-flip transition of antiferromagnetic spins in Ni $_{81}$ Fe $_{19}$ / $α$ -Fe $_{2}$ O $_{3}$

Joonghoe Dho, C. W. Leung, Z. H. Barber +1

We report studies of exchange bias and coercivity in ferromagnetic Ni $_{81}$ Fe $_{19}$ layers coupled to antiferromagnetic (AF) (0001), (11 $2 ˉ$ 0), and (11 $0 ˉ$ 2) $α$ -Fe $_{2}$ …

Thermal relaxation of field-induced irreversible ferromagnetic phase in Pr-doped manganites

Joonghoe Dho, N. H. Hur

We have investigated the magnetic and transport properties of Pr $_{0.65}$ Ca $_{0.35}$ MnO $_{3}$ and Pr $_{0.82}$ Na $_{0.18}$ MnO $_{3}$ with almost same doping level under various magnetic f…
