New magnetic phases on chiral magenet CsCuCl$_3$ under high pressures
We study a magnetic phase diagram of CsCuCl3 by a spin wave theory. We clarify an existence of new magnetic phases, i.e. up-up-down (uud) phase and Y coplanar phase under a high pressure. We also discuss a magnetic field(H)-temperature(T) phase diagram under ambient and high pressures.
