TLDR
In this paper, the authors present a method of making MAGNETIZABLE ACICULAR GAMMA-FE2O3 PARTICLES MODIFIED with AMOUNTS COBALT OXIDE.Abstract:
METHOD OF MAKING MAGNETIZABLE ACICULAR GAMMA-FE2O3 PARTICLES MODIFIED WITH AMOUNTS COBALT OXIDE, WHICH PARTICLES ARE USEFUL FOR MAKING MAGNETIC RECORDING TAPE OF HIGH COERCIVITY AFFORDING SUPERIOR ABILITY TO STORE HIGH FREQUENCY INFORMATION. EVEN HIGHER COERCIVITY MAY BE ATTAINED BY CONTROLLING THE HEATING STEPS IN MAKING THE NOVEL PARTICLES TO PROVIDE UP TO 20% FEO BY WEIGHT OF THE TOTAL IRON OXIDE.read more

Patent
Magnetic particles for use in separations
TL;DR: A process for the preparation of magnetic particles to which a wide variety of molecules may be coupled is described in this article, where the magnetic particles can be dispersed in aqueous media without rapid settling and conveniently reclaimed from media with a magnetic field.

Silanized biodegradable super paramagnetic metal oxides as contrast agents for imaging the gastrointestinal tract
TL;DR: In this article, the in-vivo use of biologically degradable and metabolizable superparamagnetic metal oxides as MR contrast agents was proposed. But the method is not suitable for in vitro applications.

Mössbauer emission spectroscopy study of cobalt-surface-doped acicular magnetite particles
M. Sharrock,P. Picone,A. Morrish +2 more
TL;DR: In this article, a portion of the cobalt was found to be incorporated into a composition approximating that of cobalt ferrite (CoFe 2 O 4 ), which is the material responsible for increasing the coercivity of the particles.

Process for preparing magnetic iron oxide and magnetic iron oxide produced thereby
TL;DR: In this article, the surface of needle-like particles of magnetic iron oxide with a cobalt compound was placed in a unidirectionally oriented magnetic field thereby orienting the particles in the direction of the magnetic field.
