    <dcterms:abstract xml:lang="eng">We show that upon exposure to a remote dc hydrogen plasma, the magnetic and electronic properties of the dilute magnetic semiconductor Ga&lt;sub&gt;1-x&lt;/sub&gt;Mn&lt;sub&gt;x&lt;/sub&gt;As change qualitatively. While the as-grown Ga&lt;sub&gt;1-x&lt;/sub&gt;Mn&lt;sub&gt;x&lt;/sub&gt;As thin films are ferromagnetic at temperatures T less, similar 70 K, the samples are found to be paramagnetic after the hydrogenation, with a Brillouin-type magnetization curve even at T=2 K. Comparing magnetization and electronic transport measurements, we conclude that the density of free holes p is significantly reduced by the plasma process, while the density of Mn magnetic moments does not change.</dcterms:abstract>
