<p>Here we show that Gallium-Substituted -Fe2O3 nanoparticles are easily stabilized in</p>
<p>aqueous media having at the same time small interparticle magnetic interactions and huge</p>
<p>coupling with the lattice such that torques at the nanoscale can be efficiently applied.</p>
<p>Moreover, under ac magnetic fields of 0<f<1000 Hz this torque is applied without heat</p>
<p>losses while the region f=10-120 kHz can be explored to dissipate heat.</p>
<p>It is shown that the specific power of Gallium-Substituted -Fe2O3 nanoparticles is larger</p>
<p>than those of γ-Iron Oxide nanoparticles currently used in magnetic hyperthermia.</p>
<p>In this view, Gallium-Substituted -Fe2O3 nanoparticles are expected to be useful tools to</p>
<p>efficiently apply mechanical forces to induce cellular apoptosis and to discern between</p>
<p>mechanical and thermal contributions to cellular apoptosis currently under debate.</p>
