This latter is characterized by a distortion from NaCl to rhomboherdral structure; but for the chromide Cr the structure is still cubic when there is a magnetic transition from paramagnetic to antiferromagnetic state.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">Best regards</div></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div style="font-family:monospace"><div><font size="2"><span style="color:rgb(0,0,255)">Mr: A.Reggad</span> <br><span style="background-color:rgb(238,238,238)"><span style="color:blue">Laboratoire de Génie Physique</span></span><br></font></div><font size="2"><span style="color:rgb(0,0,255)">Université Ibn Khaldoun - Tiaret</span><br></font></div><div><font size="2"><span style="font-family:monospace"><span style="color:rgb(0,0,255)">Algerie</span></span></font><br></div><div><div><br><span style="font-family:'times new roman',serif"><span style="color:blue"></span></span><br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
