TL;DR
This paper explores the microscopic origins of strong magnetic fields in compact stars, focusing on ferromagnetic order and spin density waves in quark matter using Fermi liquid theory and the NJL model.
Contribution
It introduces a microscopic explanation for strong magnetic fields in compact stars through ferromagnetic and spin density wave states in quark matter.
Findings
Ferromagnetic order can occur in quark matter.
Spin density waves may appear within the NJL model.
Implications for magnetic properties of compact stars are discussed.
Abstract
Some magnetic properties of quark matter and a microscopic origin of the strong magnetic field in compact stars are discussed; ferromagnetic order is discussed with the Fermi liquid theory and possible appearance of spin density wave is suggested within the NJL model. Implications of these magnetic properties are briefly discussed for compact stars.
