Doping can excite a chargedensitywave weakening the spin density wave against the stability of the ferromagnetic state.
掺杂能激发电荷密度波，从而削弱了自旋密度波，最终不利于铁磁态的稳定。

"If it is true that the pseudogap is a charge-densitywave, that would be a major, major outcome because people have been looking for this for the past decade," he said.
