== Abstract ==<br />
<br />
<p>This study investigates the linear stability of double-diffusive convection in magnetic nanofluids (MNFs) within a horizontal porous medium, accounting for field&ndash;dependent viscosity (FDV). A modified Buongiorno&ndash; type model incorporates Brownian motion, thermophoresis, magnetophoresis, and Darcy resistance. The resulting eigenvalue problem is solved via a Chebyshev pseudospectral&ndash;QZ algorithm under rigid&ndash;rigid (RR), rigid&ndash;free (RF), and free&ndash;free (FF) boundary conditions for both water&ndash;based (W b) and ester&ndash;based (E b) MNFs. Results show that magnetic and solutal effects lower the critical Rayleigh number (Ra c) from the classical Darcy&ndash;B&eacute;nard limit of&asymp;39.48 to as low as &asymp;23.8, indicating enhanced instability. In contrast, increasing the FDV coefficient (&delta;), Langevin parameter (&alpha;</p><br />
