are controllable by an external magnetic field. It is well known for its unique property of …

Colloidal ordering from phase separation in a liquid-crystalline continuous phase

JC Loudet, P Barois, P Poulin - Nature, 2000 - nature.com
Some binary mixtures exist as a single phase at high temperatures and as two phases at
lower temperatures; rapid cooling therefore induces phase separation that proceeds through …
