Controlling an altermagnetic spin density wave in the kagome magnet CsCr3Sb5.

Key Points

• This study explores the control of charge density waves and their relationship with spin density waves in kagome magnets.
• Utilized external magnetic fields to tune the amplitude and phase of charge density waves.
• Observed domain switching and stripe sliding in response to magnetic modulation.
• Charge density waves can be effectively tuned, indicating strong coupling to the altermagnetic ground state.
• Findings reveal new insights into symmetry-breaking and electronic correlations in kagome materials.
