The phrase "a decrease in magnitude" is correct and usable in written English.
It can be used in contexts discussing changes in size, intensity, or significance, often in scientific or analytical discussions.
Example: "The study showed a decrease in magnitude of the earthquake's aftershocks over the following weeks."
Alternatives: "a reduction in size" or "a decline in intensity."
The excitation spectrum of photodilation shows a decrease in magnitude with increasing wavelength (Supplementary Fig. 2).
DSC indicated higher Tg's compared with other pHEMA data in the literature, with a decrease in magnitude of the Tg occurring with increasing titania content.
The numerical examples demonstrate the increase of the convergence rate from first to second order and show a decrease in magnitude of the error.
The crust mantle layering leads to a decrease in magnitude of the onshore horizontal vectors of LYR compared to HOM (Fig. 4b).
In Fig. 4c, we note a decrease (in magnitude) of the force (F_1) on the asperity and a corresponding increase of the force (F_2) on the weak zone.
At the shallower parts, σ 1 corresponds to vertical stress (σ V) because the transition of the stress regime can be expected by a decrease in magnitude of the horizontal stress (σ Hmax = σ 2, σ Hmin = σ 3) in compressional subduction tectonics due to convex upward flexure of the upper crust.
Upon illumination, it is apparent that FcTMA2+ is reduced to FcTMA+ at the thylakoid membranes, as there is an increase in the magnitude of the generation current and a decrease in the magnitude of the collection current.
These earthquakes led to a decrease in the magnitude of stress in the Kamaishi regions after 1 year following the mainshock.
Local regions of enhanced flexibility or chain compaction are characterized by a decrease in the magnitude of the residual dipolar couplings.
During La Niña events 71% of models actually show a decrease in the magnitude of the NINO3.4 SST anomalies in E20C, while increases of 50, 58, and 67% are evident for the later periods (with E21C and L21C values again obtained under the RCP8.5 scenario).
This is attributed to a decrease in the magnitude of roughness-induced crack closure and the effective stress intensity range ΔKeff,th in the harmonic structured Ti 6Al 4V alloy due to the presence of fine grains.
