The hexaferrites of different compositions from the BaO–NiO–Fe2O3 ternary phase diagram
were prepared by a wet chemical process of gel-to-crystallite conversion. Herein, the …

Nanocrystalline NiFe2O4 spinel ferrites with various grain sizes have been synthesized by
ball milling the bulk NiFe2O4. The average grain sizes were estimated from the X-ray line …

A phenomenological approach for polycrystalline exchange-bias bilayers is proposed which
explains the coercivity enhancement as well as its temperature and coupling strength …

Nanoscale particles of BaFe12O19 in the size range 10–20 nm have been prepared at a
substantially low temperature of 425° C by a citrate precursor method. The low-temperature …

Nanosize particles of CoFe/sub 2/O/sub 4/have been synthesized by the citrate precursor
technique. Considerably higher coercive force (1.68 kOe) than that obtained by the …

A novel method for the preparation of nanoparticles of barium hexaferrite is realized by the
gel-to-crystallite (GC) conversion method. Here, gels of Fe (OH) 3· x H 2 O, 70< x< 110, were …

We report the structural and magnetic properties of arc-melted Fe-doped Mn 5 Ge 3 alloys.
In this study, Mn 5− x Fe x Ge 3 (x= 0.15, 0.3, and 0.5) alloys were subjected to DC magnetic …

The anomalous Hopkinson maximum is observed in Gd (0001) thin films at 289±1 K. This
value lies about 3 K below the bulk Curie temperature. The incoherent rotations of the …

The magnetic properties of Bi 1-x Ca x Fe 1-y Ti y O 3-δ (BCFO: y= 0 and BCFTO: x= y)
nanoparticles are studied across a wide range of temperatures (20 K to 960 K) for different …

Abstract Polycrystalline Fe doped NiO was prepared by the solid state method with the aim
of exploring its suitability as a functional material for spintronics applications. Phase pure …
